[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figures 1-8 As shown, this embodiment of the invention provides an auxiliary mechanical structure for applying negative pressure hair removal wax, including a handheld shell 100, the outside of which is covered with a protective layer 102, which is a silicone layer, to help improve the comfort of holding the hand.

[0038] The lower end of the handheld housing 100 is connected to the massage end 103. The massage end 103 is provided with a massage component for massaging the skin surface. The upper end of the handheld housing 100 is provided with an end cap 101. The handheld housing 100 where the end cap 101 is located is provided with a liquid supply component for providing care liquid to the massage component. The liquid supply component can provide sufficient care liquid to the skin surface.

[0039] The massage component includes a massage disc 400, with multiple massage strips 404 arranged in an array at the lower end of the massage disc 400. The lower end face of each massage strip 404 is provided with a massage groove 403. The massage disc 400 has a buffer cavity 402 inside, and the bottom of the buffer cavity 402 is provided with a drain hole 401 for draining liquid. The drain hole 401 is located between adjacent massage strips 404. The upper end of the massage disc 400 is connected to a guide tube 407 through a floating mechanism. The guide tube 407 has a guide channel 408 inside, and the upper end of the guide tube 407 is connected to a liquid supply component.

[0040] The guide tube 407 is connected to a massage drive mechanism for rotating it. The massage drive mechanism can drive the guide tube 407 to rotate, and the guide tube 407 drives the massage disc 400 to rotate, so that the massage strip 404 and massage groove 403 at the lower end of the massage disc 400 rotate and press on the skin surface, making the care solution easier to absorb.

[0041] The handheld outer shell 100 is also equipped with a negative pressure component that generates negative pressure at the massage end 103. The negative pressure component is associated with the massage drive mechanism. When the massage drive mechanism is working, the negative pressure component will also work. When the lower end of the massage end 103 comes into contact with the skin, it will generate negative pressure, so that the massaged area is in a negative pressure state. The negative pressure adsorption can slightly lift the skin, open the pores, facilitate the penetration of hair removal wax, and improve the hair removal effect. The lower end of the massage end 103 is wrapped with a silicone layer to improve the contact effect with the skin.

[0042] The negative pressure component includes a first transmission wheel 504 disposed at the output end of the massage drive mechanism. A mounting area corresponding to the first transmission wheel 504 is provided at the end of the transmission shaft 509. An exhaust port is provided on the surface of the handheld housing 100, and an exhaust port 107 is provided at the exhaust port location. An exhaust end cover 106 is threaded to the outer end of the exhaust port 107. Exhaust holes are evenly distributed at the end of the exhaust end cover 106. A reduction gearbox 507 is fixedly disposed at the exhaust port location. A negative pressure blade 508 is provided at the output end of the reduction gearbox 507, and a second transmission wheel 506 is provided at the input end of the reduction gearbox 507. The second drive wheel 506 is connected to the first drive wheel 504 by a drive belt 505. When the drive shaft 509 rotates, the first drive wheel 504 drives the second drive wheel 506 to rotate through the drive belt 505. The second drive wheel 506 drives the negative pressure blade 508 to rotate through the reduction gearbox 507. The negative pressure blade 508 blows the airflow inside the handheld housing 100 outward, thus creating a negative pressure state inside the handheld housing 100. The outside of the handheld housing 100 is also provided with an air intake adjustment component. By adjusting the air intake on the outside of the handheld housing 100, the negative pressure value at the bottom of the massage end 103 can be adjusted.

[0043] This application utilizes a negative pressure structure to facilitate the discharge of care solution from the liquid supply component. Traditional discharge methods rely on gravity, while this application utilizes negative pressure for discharge, making application more convenient. Even when the product is placed horizontally, the discharge of care solution is not affected.

[0044] When changing the contact lens solution midway, this negative pressure can be used to suck out the remaining solution, a function that traditional equipment does not have.

[0045] The air intake adjustment component includes an inner end cap 109 disposed on the outside of the handheld housing 100. The end face of the inner end cap 109 is provided with three arrayed first vent holes 110. An adjustment end cap 108 is rotatably fitted to the outer end of the inner end cap 109. The end of the adjustment end cap 108 is provided with three arrayed second vent holes 111. The second vent holes 111 match the first vent holes 110. By rotating the offset between the adjustment end cap 108 and the inner end cap 109, the overlap of the first vent holes 110 and the second vent holes 111 can be adjusted. In this way, the size of the air intake can be adjusted, which indirectly adjusts the negative pressure at the end of the massage end 103.

[0046] The massage drive mechanism includes a drive worm gear 500 fixedly disposed on the outside of the guide tube 407. A rotating ring 501 is rotatably disposed at the lower end of the drive worm gear 500. The outer side of the rotating ring 501 is connected and fixed to the inner wall of the handheld housing 100 through an outer ring positioning rod 502. A drive worm 503 is engaged on the outer side of the drive worm gear 500. The drive worm 503 is sleeved on the outer side of the transmission shaft 509. One end of the transmission shaft 509 is rotatably connected to the inner wall of the handheld housing 100, and the other end is connected to the output end of the drive motor. The drive motor is installed on the inner wall of the handheld housing 100. Under the action of the drive motor, the transmission shaft 509 drives the drive worm 503 to rotate. The drive worm 503 drives the guide tube 407 to rotate through the drive worm gear 500, providing power for the massage.

[0047] The handheld housing 100 also has a battery inside for power supply. The charging end of the battery has a charging interface 105. The charging interface 105 is embedded in the surface of the handheld housing 100. The surface of the handheld housing 100 also has a switch 104 that is electrically connected to the drive motor and the battery to control the operation of the device.

[0048] The floating mechanism includes a floating sleeve 406 connected to the upper end of the massage disc 400. The upper end of the floating sleeve 406 is provided with a sliding inner cavity that matches the bottom of the guide tube 407. The outer side of the bottom of the guide tube 407 is provided with a limiting protrusion 410. The inner cavity of the floating sleeve 406 is provided with a limiting groove that matches the limiting protrusion 410. The guide tube 407 and the floating sleeve 406 are connected by a floating spring 409. During massage, by pressing down on the massage disc 400, the guide channel 408 can slide inside the floating sleeve 406, so that the bottom of the handheld outer shell 100 can contact the skin, complete the lower port sealing, and provide conditions for negative pressure. When released, the massage disc 400 will return to its original position under the action of the floating spring 409.

[0049] The liquid supply component includes a nursing cartridge 300 for storing nursing solution. The inner wall of the handheld housing 100 has a loading cavity 303 that matches the nursing cartridge 300. A connecting pipe 304 is provided at the lower end of the nursing cartridge 300. A throttling mechanism is provided between the connecting pipe 304 and the guide pipe 407, which can adjust the discharge speed of the nursing solution. A piston plate 301 is slidably provided at the upper port of the loading cavity 303. An inner ring is provided on the inner side of the top of the nursing cartridge 300 to limit the piston plate 301. Force is required to pull the piston plate 301 out of the nursing cartridge 300 later. A rubber ring is provided on the outer side of the piston plate 301. To aid sealing, a handle 302 is located at the center of the upper end of the piston plate 301. By pulling the handle 302, the piston plate 301 can be moved. In use, the nursing cartridge 300 is removed, filled with nursing solution, and then sealed by the piston plate 301. The nursing cartridge 300, now fully loaded with nursing solution, is then installed in the loading cavity 303. The nursing cartridge 300 is made of transparent material, and an observation window is provided on the outside of the handheld casing 100 containing the nursing cartridge 300 to observe the amount of nursing solution in the cartridge 300. As the nursing solution is used, the piston plate 301 will also move downwards to prevent nursing solution residue from remaining on the inner wall of the nursing cartridge 300.

[0050] The massage disc 400 is also equipped with a heating wire inside, which prevents the massage disc 400 from being too cold and affecting the massage experience. A little heating also helps the absorption of the care solution.

[0051] The throttling mechanism includes a throttling valve body 205 rotatably mounted on the upper end of the guide tube 407. The outer side of the throttling valve body 205 is connected to the inner wall of the handheld housing 100 via a positioning rod. The upper end of the throttling valve body 205 is provided with a socket for easy insertion into the end of the connecting tube 304. A sealing ring matching the outer side of the connecting tube 304 is provided at the socket position. A throttling slot 204 is provided on the outer side of the throttling valve body 205, which cuts off the liquid guiding channel. A throttling valve plate 203 is slidably fitted in the throttling slot 204. An adjusting screw sleeve 201 is fixedly provided at the end of the throttling valve plate 203. An adjusting screw is threaded to one end of the handheld housing 100. The adjusting screw is rotatably connected to the handheld housing 100. A throttling knob 200 is fixedly provided at the end of the adjusting screw. A scale ring 202 corresponding to the throttling knob 200 is provided on the outside of the handheld housing 100. An indicator arrow is provided on the surface of the throttling knob 200. In use, the adjusting screw and the adjusting screw sleeve 201 are rotated relative to each other by the throttling knob 200. Under the action of the thread, the throttling valve plate 203 slides along the inner wall of the throttling slot 204, thereby cutting off the liquid guiding channel inside the throttling valve body 205. This allows control of the liquid flow rate to match different application needs.

[0052] The massage disc 400 is also provided with a liquid-pushing plate 405 that matches the inner wall of the massage end 103. The liquid-pushing plate 405 is inclined to the mass of the massage disc 400. The massage disc 400 is made of elastic colloid. When the massage disc 400 rotates, the nursing liquid on the inner wall of the massage end 103 will be scraped downward.

[0053] Working principle: In actual use, the massage disc 400 is pressed onto the skin surface, and then the massage drive mechanism works, so that the massage strip 404 and massage groove 403 at the lower end of the massage disc 400 rotate and press the skin surface. At this time, when the drive shaft 509 rotates, the first drive wheel 504 drives the second drive wheel 506 to rotate through the drive belt 505. The second drive wheel 506 drives the negative pressure blade 508 to rotate through the reduction gearbox 507. The negative pressure blade 508 blows the airflow inside the hand-held housing 100 outward, thus creating a negative pressure state inside the hand-held housing 100. The negative pressure can lift the skin at the massage position, which helps the skin absorb the care solution. At the same time, the negative pressure structure can also help the care solution flow out from the liquid supply component.

[0054] By driving the adjusting screw and adjusting sleeve 201 to rotate relative to each other through the throttling knob 200, the throttling valve plate 203 slides along the inner wall of the throttling slot 204 under the action of the thread, thereby cutting off the liquid guiding channel inside the throttling valve body 205. This allows the flow rate of the liquid to be controlled in order to match different application needs.

[0055] By rotating the inner end cap 109 and the inner end cap 109, the overlap of the first vent 110 and the second vent 111 can be adjusted, thereby adjusting the negative pressure at the end of the massage end 103 to meet different application needs.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
